Sistema FOQuE para expansão semântica de consultas baseada em ontologias difusas
Abstract
As availability of data from several areas of knowledge grows, it is even more necessary to
develop effective techniques to retrieve the desired information, aiming to reduce irrelevant
answers and ensure that relevant results are not ignored. Considering this context, we present
the FOQuE system, developed to perform query expansion in order to retrieve semantically
relevant and broad results. Based on fuzzy ontologies, this system is able to obtain
approximate results that satisfy user requirements according to expansion parameters defined
by the user. The additional answers retrieved by the FOQuE system are classified according to
the semantic expansion performed and the relevance to the query, therefore it is possible to
improve results that are presented to the user.
